ACTION: Final rule.
SUMMARY: We are adopting a new
airworthiness directive (AD) to
supersede AD 2008–11–17, which
applies to certain Air Tractor, Inc.
Models AT–200, AT–300, AT–400, AT–
500, AT–600, and AT–800 series
airplanes. AD 2008–11–17 currently
requires you to install an overturn skid
plate kit or a modification to the
overturn skid plate already installed.
Since we issued AD 2008–11–17, the
manufacturer has notified us that Model
AT–401B airplanes also need a
modification to the overturn skid plate.
Consequently, this AD would retain the
actions of AD 2008–11–17 and add the
requirement to modify the overturn skid
plate installed on Model AT–401B
airplanes. We are issuing this AD to
prevent the front and rear connections
of the overturn skid plate to the airplane
from breaking, which could allow
foreign debris to enter the cockpit
during an airplane overturn. This
condition, if not corrected, could lead to
pilot injury.
DATES: This AD becomes effective on
January 28, 2009.
On January 28, 2009, the Director of
the Federal Register approved the
incorporation by reference of Snow
Engineering Co. Service Letter #97,

SUPPLEMENTARY INFORMATION:
Discussion
On October 14, 2008, we issued a
proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) to
include an AD that would apply to
certain Air Tractor, Inc. Models AT–
200, AT–300, AT–400, AT–500, AT–
600, and AT–800 series airplanes. This
proposal was published in the Federal
Register as a notice of proposed
rulemaking (NPRM) on October 23, 2008
(73 FR 63096). The NPRM proposed to
supersede AD 2008–11–17 with a new
AD that would retain the actions of AD
2008–11–17 and add the requirement to
modify the overturn skid plate installed
on Model AT–401B airplanes.
Comments
We provided the public the
opportunity to participate in developing
this AD. We received no comments on
the proposal or on the determination of
the cost to the public.
Conclusion
We have carefully reviewed the
available data and determined that air
safety and the public interest require
adopting the AD as proposed except for
minor editorial corrections. We have
determined that these minor
corrections:
• Are consistent with the intent that
was proposed in the NPRM for
correcting the unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM.
Costs of Compliance
We estimate that this AD affects 1,309
airplanes in the U.S. registry.
In determining the total cost on U.S.
operators, we presume all airplanes in
the U.S. fleet have an overturn skid
plate installed (as required by AD 2002–
25–09) and the only cost is to
incorporate the modification kit P/N
11411–1–501. We estimate the following
costs to do the modification of installing
the overturn skid plate modification kit
P/N 11411–1–501 to those planes that

Authority for This Rulemaking
Title 49 of the United States Code
specifies the FAA’s authority to issue
rules on aviation safety. Subtitle I,
Section 106 describes the authority of
the FAA Administrator. Subtitle VII,
Aviation Programs, describes in more
detail the scope of the agency’s
authority.
We are issuing this rulemaking under
the authority described in Subtitle VII,
Part A, Subpart III, Section 44701,
‘‘General requirements.’’ Under that
section, Congress charges the FAA with
promoting safe flight of civil aircraft in
air commerce by prescribing regulations
for practices, methods, and procedures
the Administrator finds necessary for
safety in air commerce. This regulation
is within the scope of that authority
because it addresses an unsafe condition
that is likely to exist or develop on
products identified in this AD.
Regulatory Findings
We have determined that this AD will
not have federalism implications under
Executive Order 13132. This AD will
not have a substantial direct effect on
the States, on the relationship between
the national government and the States,
or on the distribution of power and
responsibilities among the various
levels of government.
For the reasons discussed above, I
certify that this AD:
1. Is not a ‘‘significant regulatory
action’’ under Executive Order 12866;
2. Is not a ‘‘significant rule’’ under the
DOT Regulatory Policies and Procedures
(44 FR 11034, February 26, 1979); and
3. Will not have a significant
economic impact, positive or negative,
on a substantial number of small entities
under the criteria of the Regulatory
Flexibility Act.
We prepared a summary of the costs
to comply with this AD (and other
information as included in the
Regulatory Evaluation) and placed it in
the AD Docket. You may get a copy of
this summary by sending a request to us
at the address listed under ADDRESSES.
Include ‘‘Docket No. FAA–2008–1120;
Directorate Identifier 2008–CE–064–

SUMMARY: We are adopting a new
airworthiness directive (AD) for all
McDonnell Douglas airplanes identified
above. This AD requires repetitive
inspections of the lower skin and
stringers at stations Xw=408 and
Xw=¥408, and corrective actions if
necessary. This AD results from reports
of cracks in the skins and stringers at
the end fasteners common to the
stringer end fittings at stations Xw=
408 and Xw=¥408 wing splice joints.
We are issuing this AD to detect and
correct fatigue cracking in the skins and
stringers at the end fasteners common to
the stringer end fittings at certain station
and wing splice joints, which could
result in wing structure that might not
sustain limit load, and consequent loss
of structural integrity of the wing.

except for minor editorial corrections. We have determined that these
minor corrections:
Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.
Costs of Compliance
We estimate that this AD affects 1,309 airplanes in the U.S.
registry.
In determining the total cost on U.S. operators, we presume all
airplanes in the U.S. fleet have an overturn skid plate installed (as
required by AD 2002-25-09) and the only cost is to incorporate the
modification kit P/N 11411-1-501. We estimate the following costs to do
the modification of installing the overturn skid plate modification kit
P/N 11411-1-501 to those planes that
[[Page 78945]]
currently have the overturn skid plate installed:
----------------------------------------------------------------------------------------------------------------
Total cost per Total cost on
Labor cost Parts cost airplane U.S. operators
----------------------------------------------------------------------------------------------------------------
2 work-hours x $80 per hour = $160........................... $42 $202 $264,418
----------------------------------------------------------------------------------------------------------------
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, Section 106 describes the
authority of the FAA Administrator. Subtitle VII, Aviation Programs,
describes in more detail the scope of the agency's authority.
We are issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701, ``General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this AD.
Regulatory Findings
We have determined that this AD will not have federalism
implications under Executive Order 13132. This AD will not have a
substantial direct effect on the States, on the relationship between
the national government and the States, or on the distribution of power
and responsibilities among the various levels of government.
For the reasons discussed above, I certify that this AD:
1. Is not a ``significant regulatory action'' under Executive Order
12866;
2. Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979); and
3. Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
We prepared a summary of the costs to comply with this AD (and
other information as included in the Regulatory Evaluation) and placed
it in the AD Docket. You may get a copy of this summary by sending a
request to us at the address listed under ADDRESSES. Include ``Docket
No. FAA-2008-1120; Directorate Identifier 2008-CE-064-AD'' in your
request.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the Federal Aviation Administration amends part 39 of the Federal
Aviation Regulations (14 CFR part 39) as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by removing Airworthiness Directive (AD)
2008-11-17, Amendment 39-15540 (73 FR 31351, June 2, 2008), and adding
the following new AD:
2008-26-01 Air Tractor, Inc.: Amendment 39-15767; Docket No. FAA-
2008-1120; Directorate Identifier 2008-CE-064-AD.
Effective Date
(a) This AD becomes effective on January 28, 2009.
Affected ADs
(b) This AD supersedes AD 2008-11-17, Amendment 39-15540.
Applicability
(c) This AD applies to the following airplane models and serial
numbers that are certificated in any category:
------------------------------------------------------------------------
Group 1 models Serial Nos.
------------------------------------------------------------------------
AT-250, AT-300, AT-301, -0001 through -1196.
AT-302, AT-400, AT-400A,
AT-401, AT-401A, AT-402,
AT-402A, and AT-402B.
AT-501, AT-502, AT-502A, -0001 through -2620.
and AT-502B.
AT-602................... -0337 through -1153.
AT-802A.................. -0003 through -0282.
------------------------------------------------------------------------
------------------------------------------------------------------------
Group 2 models Serial Nos.
------------------------------------------------------------------------
AT-401B.................. -0952 through -1196.
------------------------------------------------------------------------
Unsafe Condition
(d) Since we issued AD 2008-11-17, the manufacturer has notified
us that Model AT-401B airplanes also need a modification to the
overturn skid plane. Consequently, this AD retains the actions of AD
2008-11-17 and adds the requirement to modify the overturn skid
plate installed on Model AT-401B airplanes. We are issuing this AD
to prevent the front and rear connections of the overturn skid plate
to the airplane from breaking, which could allow foreign debris to
enter the cockpit during an airplane overturn. This condition, if
not corrected, could lead to pilot injury.
